Subject: [PATCH] net/qede: fix L2-handles used for RSS hash update
|
|
|
a6040a |
|
|
|
a6040a |
Fix fast path array index which is used for passing L2 handles to RSS
|
|
|
a6040a |
indirection table, properly distribute rxq handles for indirection table.
|
|
|
a6040a |
Currently, it is using the local copy of indirection table. When the RX
|
|
|
a6040a |
queue configuration changes the local copy becomes invalid.
|
|
|
a6040a |
|
